I know it ! It was built in France, in Nantes. As I live 70 km away from this city I’ve seen it a few times. It’s a whole big steampunk project : Les machines de l’ïle [http://www.lesmachines-nantes.fr/] . They manage 3 or 4 projects like this elephant, or creating an enormous carousel, with many wood and iron creatures inspired from sea. Take a look, it’s really interesting !
